EA41

The updated version of the EA4, the Nitecore EA41 improves on the original with a new switch, slightly higher maximum output, and a very useful 1lm low mode.
* 960lm Turbo
* 510lm High
* 120lm Medium
* 40lm Low
* 1lm Micro

I have the original EA4 and it is great. I never had an issue with the switch, and from the reviews floating around it is certainly an improvement.

I couldn't find a selfbuilt review, so here is a mini review from BLF

Perfect for all those AA eneloops (takes 4).

  got one, great torch for the price. my switch is reliable, but just a bit finnicky and hard to get used to its function. hopefully the new switch is more user friendly

  thinking about getting another…

  Mine arrived last week using the same code. Initial impressions are good, good build quality.

  i got this one on the previous deal and i have the ea4 as well. i think this ea41 has heat issues, as it felt hotter than the ea4 on the brightest 'non-turbo' setting after a while.

  i put it down as the led outputting far more lumens, and the body is not suitable to handle the heat with the newer led.

  am always a fan of the 4xAAs as it seems to be the ideal size/weight/output/lifespan ratio to me.

  will post a more detailed review on cpf…

    feeling hotter is not a bad thing, that means the heatsinking is working well and dissipating the heat from the led to the body of the light, that's exactly what you want. I will be more concerned if it felt cooler, as built up of heat that is trapped at the led can lead to faster degradation of the phosphor and reducing the output of the light

      would be true if you didn't measure the internal temp and based it entirely on 'skin feels' and the body is made of plastic.

      a properly built body that dissipates heat quickly would feel (and measure) cooler than one that is inefficient. and if you have been running the torch till it goes flat at the max, there are a lot of factors involved but the form factor remains somewhat the same.

      considering Ea41 and Ea4 is of almost identical body. How could you say the Ea41 has more efficient heatsink design?
      That don't make sense.

      have you owned and used a sunwayman M40a? it's highest output is higher than both 'high' setting (not referring to turbo) Ea41 and Ea4 and does not feel like it's cooking your hand. the internal temp measures lower too.

      so i struggle to understand your logic.

        Agree, as your hand will be touching the heatsink, if it feels hotter it is pumping out more heat. The hotter the heatsink, for a given design, the hotter the element inside it is cooling.
        I have an ea4 and it is great. Might get another one as good for cars when AA batteries last a while between charges unlike li-ion.

        slowmo, if you read my comment, you will realise that I didn't say the EA41 has a more efficient heatsink design, there are other factors at play that could make the EA41 feel hotter to the touch. How well the heat sink sits in the body, thermal paste, soldering could play a part in heat distribution.

        I don't have the sunwayman M40a, but have many others. The M40a could be dispersing the heat over a wider area, could have thicker aluminum walls to draw away heat further away from the head and dispersing it better across the body and therefore feel cooler to the touch.

        To help you understand, try putting hot water in a stainless steel mug and a ceramic mug. The stainless steel mug will feel hotter to the touch, compared to the ceramic mug, does this make it inefficient to the ceramic cup?, No, it is in fact working very well at drawing the heat away, that's why it is hot. Over time, the water in the stainless steel mug will cool down much faster, therefore it is a more effective heatsink.

        Hope it's more clearer to you now.

        @haz:
        err.. you replied to my comment which was specifically talking about the ea41 and I was comparing to ea4.

        would be nice if you clarified up front that you are not.

        as for the analogy, you forgot about the constant heat over time (the ceramic mug just takes longer to heat up) and again, you are replying to my post thus the context to your comparison is irrelevant in this case.

        @skyva: i have started to trial putting both EAs in both my cars and I am starting to notice the heat (due to parking it outdoors) affects the batteries.

        it's worth considering that factor too.

        I'm paranoid, but I have a hand crank torch in the boot in the event that all batteries died.

  How is this compared with LED Lenser M7 ? other than 4 x AAA battery?

    throw and output is a big difference between the two, as well as size. Not to mention that the AAs lasts a bit longer. so for the price, it might not be as value for money AA vs AAA (unless you hoarded the AAAs eneloops in the recent deals)

    it's a personal preference thing. I got the EA41 because I was pleased with the nitecore EA4 that I've got previously, and I want a few that I can take for night walks. i make it a point to get AAs torches only purely due to my AA eneloop stock (I've over 80 eneloops of AAs used for almost everything at home and flash photography)

    in my case, there is no practical reason to buy a non-AA torch since I just need to carry a backup stash of AAs and it can be used to replenish which ever device that ran out.
